How we scored it
C8 capryloyl (oleochemical caprylic acid) amide-linked to collagen hydrolysate peptides; acid-chloride reagent leaves no mass; any Na/K counter-ion is mineral. All natural: 1.00.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Dominant route acylates collagen hydrolysate (from bovine, porcine or fish skin and hide) with capryloyl chloride made from coconut or palm kernel caprylic acid. Petrochemical caprylic acid exists, so a supplier note on fatty-acid origin is advisable.
In plain English
Collagen broken into small protein fragments and attached to caprylic acid, an eight-carbon fatty acid from coconut or palm kernel oil. The fatty tail helps it cling to hair, where it is used to reduce static and condition. The collagen comes from animal skin or hide by-products.
